Abstract
The invention discloses a biodiesel pour point reducer composition containing a Tween surfactant and a preparation method thereof. The biodiesel pour point reducer composition containing the Tween surfactant is formed by mixing Tween series surfactants and a biodiesel pour point reducer, wherein the materials comprise the following components by weight percent: 5 to 10 percent of Tween 20, 0 to 5 percent of Tween 40, 5 to 10 percent of Tween 60, 40 to 60 percent of Tween 80 and 0 to 50 percent of biodiesel pour point reducer. The preparation method comprises the following steps of: mixing the raw materials and stirring the raw materials in a thermostatic water bath condition, and controlling the rotating speed to 300 revolutions per minute for 15 minutes so as to obtain the biodiesel pour point reducer composition containing the Tween surfactant. The biodiesel pour point reducer composition is added into biodiesel, so that the cold filter plugging point of the biodiesel is reduced by 7 to 12 DEG C, the condensation point of the biodiesel is reduced by 7 to 13 DEG C, and the low temperature fluidity of a biodiesel product is improved.
Description
Technical field
The present invention relates to a kind of pour point reducer composition and preparation method thereof, more specifically saying so, it is a kind of to relate to
Contain tween surfactantsPour point reducer composition of biofuel pour point depression and preparation method thereof and the application aspect traditional biofuel pour point depression.
Background technology
Quickening along with vehicle diesel oil trend in the world wide; The diesel oil demand can be increasing; And the promotion of exhausted day by day and people's environmental consciousness of petroleum resources countries in the world develop the paces of diesel oil alternative fuel; Especially got into the 90's of 20th century, biofuel has caused the attention of countries in the world governments as a kind of environmental type fuel.Biofuel (Biodiesel) is fatty acid methyl ester (Fatty Acid Ester), and chemical molecular formula is RCOOCH
3(R:C
12-24), mainly be to process for raw material by vegetables oil or animal tallow etc., be a kind of novel cleaning, renewable energy source, can substitute petrifaction diesel, directly as the fuel of oil motor, be typical " green regenerative energy sources ".Yet the condensation point of biofuel is higher, its application of limit to a great extent, and it is particularly important therefore to improve biodiesel lower-temperature fluidity.
Adding cold flow improver has become the major measure that the problem of present solution biodiesel lower-temperature fluidity difference can be taked because its add-on is few, cost is low, easy to operate.Continue to use traditional diesel pour inhibitor mostly for biofuel pour point depressant aspect both at home and abroad; Lack to biofuel outstanding effect pour point depressant; Reason is that biofuel composition and diesel oil have a great difference; Contain a large amount of saturated fatty acid methyl esters, itself zero pour is higher, uses traditional pour point depressant poor effect merely.Diesel pour inhibitor is mainly the polymer of chain-like structure, and various groups are arranged on its side chain, comprises N-alkanes hydrocarbon chain, carbonyl that length is different.Generally believe, pour point depressant be through the absorption on wax crystallization surface or with the effect of its formation cocrystallization, change the brilliant shape and size of wax, prevent that wax intergranular bonding from forming three-dimensional network-like structure, thereby reach the pour point depression effect, improve the low temperature flowability of diesel oil.The tween series of surfactants belongs to nonionogenic tenside, low price and being dissolved in the biofuel.The mechanism of action according to diesel pour inhibitor adopts tween series of surfactants and its pour point depressant commonly used on the market to carry out composite its dispersion effect on oil product wax crystalline substance that strengthens; Compsn extend into through the polar group in its molecular structure in the nucleus of fatty acid methyl ester the eutectic effect takes place with it, and non-polar group is distributed in plane of crystal and changes the crystalline interfacial property, thereby changes crystalline form and dispersion state; After in biofuel, adding said composition; It and fatty acid methyl ester generation complexing action are separated out temperature and reduce crystalline, and change the crystal growth process; Thereby change its form, and then improve the low temperature flowability of biofuel.
Summary of the invention
One of the object of the invention is in order to provide a kind of
Contain tween surfactantsThe biofuel pour point reducer composition, described biofuel pour point reducer composition can with the nucleus generation eutectic effect of fatty acid methyl ester.
Two of the object of the invention provides above-mentioned a kind of
Contain tween surfactantsThe preparation method of biofuel pour point reducer composition.
Three of the object of the invention provides above-mentioned a kind of
Contain tween surfactantsThe application method of biofuel pour point reducer composition in the biofuel pour point depression.
Know-why of the present invention
The tween series of surfactants belongs to ester class non-ionics, can improve it with the composite use of pour point depressant and contact inadequate problem with the wax crystalline substance.Said composition extend into through the polar group in its molecular structure in the nucleus of fatty acid methyl ester the eutectic effect takes place with it, and non-polar group is distributed in plane of crystal and changes the crystalline interfacial property, thereby changes crystalline form and dispersion state; After in biofuel, adding said composition; It and fatty acid methyl ester generation complexing action are separated out temperature and reduce crystalline, and change the crystal growth process; Thereby change its form, and then improve the low temperature flowability of biofuel.
